108 SHORT NOTICES. [1900 



But probably something might be done as a preventive measure by 

 means of spray iiitf. One characteristic of the attack is that (chiefly in 

 July) the females rest by day amongst the Pine leafage, but in the dusk 

 of the eveniny they swarm about the tops of the trees. In all reasonable 

 probability good sprayings with some mixture of soft-soap with an 

 addition of paraffin or some mineral oil, as of " Anti-pest," for instance 

 (see Index), whether applied by day or in the evening, would do a deal 

 of good. In some cases knapsack sprayers would act well, and where 

 there was space for passage of horse or steam sprayers these would 

 meet any difficulty as to throwing applications to any height required. 



For previous reference to this attack, see my Annual Report for 

 1895, pp. 72-76, with figure of moth, and also of distorted shoots and 

 stunted leafage.
